i have bad service from C omcast but my t.v. has a fan that goes on loudly if my hubby watches it 24/7. the noise stops if i turn the t.v. off. I do get pixalated stations and/or the blue message box saying it will be available soon and never is. i pay for all this too! they need to come out and fix your problems. They seem to want to fix things these days so call for sure.
